Methodology — PlainWarranty

Q: How often is the data updated?

The CFPB complaint database updates on a rolling basis. PlainWarranty refreshes its database periodically to incorporate the latest records. Warranty plans, service fees, and coverage terms can change between refreshes, so verify current plan terms directly with the company before purchasing.

Q: How accurate are PlainWarranty's complaint scores and coverage matrices?

Complaint scores reflect CFPB and BBB records at the time of our last refresh, normalized against estimated customer base — they are a relative indicator, not a full picture of every customer's experience. Coverage matrices reflect publicly available plan documents and may not match custom or state-specific plan variants.

Data Sources

PlainWarranty's analysis is built from multiple publicly available and independently verifiable sources to provide objective, data-driven company comparisons:

BBB Complaint Data: Complaint patterns from the Better Business Bureau public complaint database for each home warranty company — complaint volume, resolution rates, response timeliness, and dispute frequency.
FTC Consumer Sentinel Network: Federal complaint and fraud trend data from FTC.gov Consumer Sentinel — aggregated reports filed with the Federal Trade Commission.
State Department of Insurance Filings: For states regulating home warranty companies as service contracts (e.g. NY DFS, Texas TDI, California CDI) — licensing status, market conduct exams, regulatory actions.
NAIC Consumer Information: Cross-state market conduct data from the National Association of Insurance Commissioners.
Plan Documentation: Publicly available plan documents, pricing pages, and coverage summaries from each company's website — the basis of our coverage matrices.
Industry Reports: Industry publications and consumer advocacy reports for context on market trends and company practices.

Complaint Score Calculation

Complaint scores (A through F) are calculated from three components:

Complaint Volume (normalized): Complaints are normalized relative to estimated customer base — a company with 1,000 complaints and 2 million customers scores differently than one with 1,000 complaints and 50,000 customers.
Timely Response Rate: The percentage of complaints that received a timely response from the company.
Dispute Rate: How often consumers dispute the company's complaint resolution, indicating persistent dissatisfaction.

Score thresholds (A through F) are calibrated against the full distribution of scores across all 19 companies in our database, so ratings reflect relative performance within the home warranty industry rather than absolute standards.

Coverage Matrices

Coverage matrices document what each plan covers and excludes, built from published plan documents. We track coverage for major home systems (HVAC, plumbing, electrical, water heater) and appliances (refrigerator, dishwasher, oven/range, washer/dryer, etc.) across each company's plan tiers.

Coverage matrices may not reflect custom, negotiated, or add-on plans not documented publicly. We update our database as new plan documents become available.

What PlainWarranty Is Not

PlainWarranty does not collect, solicit, or display consumer reviews. We do not accept paid placements, sponsored rankings, advertising, or affiliate commissions from any home warranty company. All rankings and scores are derived exclusively from complaint data and publicly available company documentation, ensuring our analysis remains independent and unbiased.

PlainWarranty does not sell home warranties. We do not receive compensation when you purchase a warranty from any company listed on this site.

Limitations

BBB complaint data reflects voluntary complaint filing — it represents a subset of actual customer disputes, not all customer experiences.
Customer base estimates are approximations used for normalization.
Coverage details may vary by state, plan tier, property age, and individual contract terms.
Plan documentation changes frequently — coverage matrices may not reflect the most current plans.

Processing Pipeline

Our data pipeline builds the PlainWarranty database through a multi-source research process:

Collect BBB complaint data for each home warranty company, extracting complaint volume, response rates, and dispute resolution patterns
Review publicly available plan documents from each company's website, documenting coverage items, exclusions, service call fees, and plan tiers
Check state regulatory databases for licensing status and any enforcement actions
Compute complaint scores by normalizing complaint volume against estimated customer base and weighting response timeliness and dispute rates
Build coverage comparison matrices showing item-by-item coverage across all companies and plan tiers

All complaint metrics come from BBB public records, and coverage details come from published plan documents. We do not collect, generate, or display consumer reviews.

Editorial Workflow

Content on PlainWarranty is compiled by our editorial team. Raw records from the CFPB Consumer Complaint Database, FTC Magnuson-Moss Warranty Act (MMWA) guidance, state attorney-general consumer protection filings, and published home warranty plan documentation are ingested programmatically by our ETL pipeline. Narrative framing, guide text, rankings commentary, and methodology writeups are drafted by our editorial team and then reviewed line-by-line by the PlainWarranty Editorial team at Kiznis Studio before publication. We follow the Google Search Central guidance (Danny Sullivan, February 2023; reaffirmed 2024) that editorial / human-edited workflows are acceptable when disclosed. No page on PlainWarranty is published without human review. We do not accept payment for coverage, placement, or rankings — the scores and rankings are computed directly from public data.

Frequently Asked Questions

Where does PlainWarranty's data come from?

All complaint figures come from the CFPB Consumer Complaint Database and BBB public records. Warranty obligations and disclosure standards are drawn from the FTC Magnuson-Moss Warranty Act (MMWA) and related FTC guidance. Licensing, service-contract regulation, and enforcement actions are pulled from state attorney-general and state insurance-department filings. Coverage matrices are built from each company's published plan documents.

How often is the data updated?

The CFPB complaint database updates on a rolling basis as complaints are filed and resolved. BBB records, state AG filings, and plan documents change at the source at different cadences. PlainWarranty refreshes its database periodically to incorporate the latest records. Because warranty plans, service fees, and coverage terms can change between refreshes, always verify current plan terms directly with the company before purchasing.

How accurate are PlainWarranty's complaint scores and coverage matrices?

Complaint scores reflect CFPB and BBB records available at the time of our last refresh, normalized against estimated customer base size — they are a relative indicator, not a full picture of every customer's experience. Coverage matrices reflect publicly available plan documents and may not match custom, negotiated, or state-specific plan variants. Where a data point is not available for a company or plan tier, we display "Data not available" rather than guessing.

Is PlainWarranty legal advice?

No. PlainWarranty is informational only. Nothing on this site is legal, financial, or insurance advice, and PlainWarranty is not a law firm, insurance agency, or warranty broker. For questions about your specific contract, claim, or dispute under the Magnuson-Moss Warranty Act or state law, consult a licensed attorney or your state attorney general's consumer protection office.
